Abstract
Nanometer size semiconductor nanocrystallites show a striking
evolution of electronic properties with size. These particles show a
size dependent discrete set of optical transitions which can be
assigned to "particle-in-a-sphere" quantum states. As a result these
nanocrystalites are often called "quantum dots" or "artificial atoms."
We use a variety of spectroscopic techniques to probe their electronic
structure to assess the "artificial atom" label. We then turn to
structures of dots and describe the manipulation of the dots to form
extended structures such as quantum dot superlattices or layered
organic/quantum dot light emitting devices.
